The c.77C>A (p.S26Y) alteration is located in exon 2 (coding exon 1) of the AP5S1 gene. This alteration results from a C to A substitution at nucleotide position 77, causing the serine (S) at amino acid position 26 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
